The Jedi Bendu Script
Site : Want to
read the original drafts for Star Wars? How about the rejection
letters that United Artists sent Lucas? What about essays exploring
the transformation of characters through the early material? This
site has it all, and yes, it is all authentic (most of them were
leaked in the late 70's before Lucasfilm
security tightened up and have floated the bootleg circuit for a
few decades).

Star Wars
Origins
: A great site to explore the inspirations and sources which
Lucas drew upon when writing his saga, from Flash Gordon to Lord of
the Rings to Metropolis.

Star Wars Archives: An
incredible labor of love dedicated to preserving and archiving rare
stills, videos, interviews and more. A wealth of unique and hard to
find information that lives up to its name and is an invaluable
resource.

Deleted Magic: A
mind-blowing fan documentary on the creation of Star Wars, with
emphasis on its editing. Contains every available deleted scene, as
much behind the scenes footage as there is out there and a partial
re-construction of the original "Lost Cut" including the original
alternate edit of the trench run.

Originaltrilogy.com: Fight the good
fight and get the original-original trilogy released properly. A
fantastic community of youngins and old-timers (as diverse as fans
who like the prequels to people who saw the original in 1977
and have never even seen the new films) with an emphasis on the original three films. Also
well known for its extensive preservation network of vintage video material
and fan-edits.

TheForce.Net
: The biggest and one of the oldest Star
Wars sites, with a great news network, some of the
more consistently accurate spy reports on upcoming developments, and
probably the biggest forum network of fans.

Outterim Seiges
: A great board for those looking for interesting
discussion.
